Apologies, that should be
grep("[[:digit:]]{2}", x, value=T) returns "pjhj24jhjhd"
obviously.

Subject: [R] grep(): returning the matched value
Hi,
I'm looking to use the grep function (or something else) to return the matched
pattern as opposed to the whole element. For example:
x <- c("pjhj24jhjhd")
grep("[[:digit:]]{2}", x, value=T) returns "people", whereas I simply want
"24".
Any help would be appreciated,
Thanks, Aidan
